• To replicate the experiment, you can find our experimental instructions in the folder experimental instructions. For each experiment, lab and online, we have included both a PDF with the instructions and a Qualtrics file (.QSF). Do note that the lab experiment was divided into two surveys.
• To replicate the analysis using our experimental data, it is only necessary to run the file run.do. This file will create the necessary folders for results and intermediate outputs. Before running this file, you should change the global macro RUTA, in line 25, to point to the directory containing this README file in your computer.
• The file run.do calls code/main.do, which calls the necessary files for data management and analyses.
• The raw data for the analysis is contained in the folder rawData, which contains one folder for the lab experiment and one folder for the online experiment. The folder from the laboratory experiment contains two .CSV files with the answers from the two Qualtrics surveys that compose the experiment and one .XLSX with data on body and leftover weights. The folder from the online experiment contains one .CSV file from the Qualtrics survey.

Stata version 14.2 or higher. Add-on packages are included in code/libraries/stata and do not need to be installed. The names, installation sources, and installation dates of these packages are available in code/libraries/stata/stata.trk. For the results shown in the paper, we ran the master script on XXX. The analysis required minimal memory and processing resources. It was last run on a Windows 10 Desktop with 16 gigabytes of RAM and an i7-6600 CPU 2.60 GHz processor. The runtime was XXXX.
